Description
Technical Field
The utility model relates to a cooling tower field technique, in particular to height-adjustable type cooling tower variable flow device.
Background
The water balance of the cooling tower is a core energy-saving technology of a high-efficiency refrigerating machine room and is also a key factor for success of a variable flow system of the cooling tower. The cooling tower is a device which generates steam through the contact of water and air to perform heat exchange, and the generated steam is discharged from a steam outlet, thereby reducing the temperature of the air in the tower and achieving the purpose of reducing the water temperature by dissipating the preheating generated in the industry. The cooling tower variable flow range is usually only 80% -100% without additional variable flow nozzles. After the variable flow nozzle is adopted, the change rate of the cooling water of the cooling tower can be increased to 60% -100% variable flow. There are three main types of variable flow nozzles: 1. no vertical pipe; 2. straight seaming of the side surface; 3. a V-shaped seam at the side. The variable flow nozzles of the models 2 and 3 adopt the mode of adding a straight pipe at the top of a main nozzle and opening a hole at the side surface. However, the side opening can affect the uniform water distribution effect of the variable flow nozzle, and the actual use effect is not ideal.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem, the utility model provides a scheme has solved the problem that both can adjust cooling tower variable flow volume scope and can reach the uniform water distribution effect again.
The utility model adopts the technical scheme as follows: the utility model provides a height-adjustable type cooling tower variable flow device, the key lies in: the water distribution device comprises a strip-shaped water tank, a first spray head and a height-adjustable spray head, wherein the strip-shaped water tank is provided with a plurality of water distribution holes, the first spray head is fixedly arranged in the water distribution holes, and the height-adjustable spray head is movably arranged in the water distribution holes in a penetrating mode. The effect of the above scheme is that when the water flow in the strip-shaped water tank is insufficient, only the first spray head can discharge water; when the water flow in the strip-shaped water tank is sufficient, the first spray head and the height-adjustable spray head can discharge water, so that the water cooling device is suitable for cooling towers with various water quantities, and the variable flow range of the cooling tower is expanded.
The height-adjustable spray head comprises an adjusting straight pipe and a second spray head, the outer pipe wall of the adjusting straight pipe is in threaded connection with the water distribution hole, the upper portion of the adjusting straight pipe extends into the strip-shaped water tank, and the lower portion of the adjusting straight pipe is fixedly connected with the second spray head. The effect of this scheme is can be according to the water yield in the bar basin, and the height that the straight tube stretched into in the bar basin is adjusted in the debugging, makes the upper portion of adjusting the straight tube submerge to expand cooling tower variable flow volume scope.
The first spray head is arranged in the middle of the strip-shaped water tank, and the height-adjustable spray heads are arranged close to two sides of the strip-shaped water tank 1. The effect of this scheme is that the variable flow range of cooling tower can be better adjusted.
The first spray head and the second spray head are both cylindrical spray heads. The effect of this scheme is that have even water distribution effect.
The first spray head and the second spray head are both oval spray heads. The effect of this scheme is that have even water distribution effect.
The first spray head and the second spray head are fan-shaped spray heads. The effect of this scheme is that have even water distribution effect.
Compared with the prior art, the height-adjustable cooling tower variable flow device provided by the utility model can adjust the height of the adjusting straight pipe extending into the strip-shaped water tank according to the water flow condition of the cooling tower, and when the water flow is insufficient, only the first spray head can discharge water; when the water flow rate does not adjust the upper end of the straight pipe, the first spray head and the second spray head can discharge water, so that the variable flow range of the cooling tower is expanded to 30% -100%; and the first spray nozzle and the second spray nozzle are both conventional spray nozzles, so that the uniform water distribution effect can be achieved, and the comprehensive energy saving rate of the cooling water system can be improved by 30%.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1-5, a height-adjustable cooling tower variable flow device comprises a bar-shaped water tank 1, wherein a plurality of water distribution holes are formed in the bar-shaped water tank 1, a first nozzle 3 is arranged in the middle of the bar-shaped water tank 1, a height-adjustable nozzle 2 is arranged near two sides of the bar-shaped water tank 1, the first nozzle 3 is fixedly installed in the water distribution holes, the height-adjustable nozzle 2 comprises an adjusting straight pipe 21 and a second nozzle 22, the outer pipe wall of the adjusting straight pipe 21 is in threaded connection with the water distribution holes, the upper part of the adjusting straight pipe 21 extends into the bar-shaped water tank 1, the lower part of the adjusting straight pipe 21 is fixedly connected with the second nozzle 22, and the first nozzle 3 and the second nozzle 22 are cylindrical nozzles, elliptical nozzles or sector nozzles.
